  • Measurement Of Resistance Or Impedance (AREA)

Abstract

Electricians can measure an earthed conductor resistance (Rsl) as permissible dummy measurements (Riso) for insulating resistance with the help of a plug-in manual probe (S3) and an in-built ohmmeter as well as a residual current (Ipe) and a contact-voltage current (Ib). The earthed conductor resistance is measured first. Test results are sent to a display device.

Description

Diese BGVA2-Steckdosenleiste soll es Unternehmen ermöglichen, auf einfache und vor allem günstige Art, den Forderungen der Unfallverhütungsvorschrift BGVA2(VBG4) § 5 für ortsveränderliche elektrische Betriebsmittel mit Hilfe von Differenzstrommessungen als RISO-Ersatzmessungen nach DIN VDE 0702 gerecht zu werden.This BGVA2 power strip is supposed to enable companies to on simple and above all cheap Type, the requirements of the accident prevention regulation BGVA2 (VBG4) § 5 for portable electrical Equipment using residual current measurements as RISO replacement measurements according to DIN VDE 0702.

Bei der jetzigen Methode ist die Verhältnismäßigkeit zwischen Risikominimierung in Bezug auf Brand- u. Personenschutz und dem finanziellem Aufwand fraglich, bzw. von vielen Unternehmen einfach nicht finanzierbar.With the current method it is proportionality between minimizing risk in relation to fire and personal security and the financial expense questionable, or by many companies simply not affordable.

Der in Schutzanspruch 1 angegebenen Erfindung, liegt das Problem zugrunde, eine ortsfeste und/oder mobile Vorrichtung (Steckdosenleiste) zu schaffen, mit der elektrotechnische unterwiesenen Personen auf einfachste Art, gefahrlos und zeiteffektiv den Schutzleiterwiderstand RSL mit Hilfe einer einstöpselbaren Sonde/Handgerät (Schutzanspruch 2) und eingebautem Ohmmeter (Schutzanspruch 2) , den Fehlerstrom IPE bei Schutzklasse I-Geräten (Schutzanspruch 3) und den Berührungsstrom IB bei Schutzklasse II-Geräten (Schutzanspruch 2 und Schutzanspruch 3) als zugelassene Ersatzmessungen für den Isolationswiderstand nach DIN VDE 0702 messen können.The invention specified in protection claim 1 is based on the problem of creating a stationary and / or mobile device (power strip) with which trained electrical engineers can easily, safely and time-effectively use the protective conductor resistance R SL with the aid of a plug-in probe / hand-held device (protection claim 2) and built-in ohmmeter (protection claim 2), the fault current I PE for protection class I devices (protection claim 3) and the contact current I B for protection class II devices (protection claim 2 and protection claim 3) as approved replacement measurements for the insulation resistance according to DIN VDE 0702 can measure.

Als erstes wird der RSL jedes einzelnen Schutzklasse I-Gerätes mit Hilfe des Handgerätes/Sonde (Schutzanspruch 2) gemessen.First, the R SL of each individual protection class I device is measured using the handheld device / probe (protection claim 2).

Die LED im Handgerät zeigt grün, wenn sich der gemessene Wert im zulässigen Bereich von 0,3 Ohm befindet. Oberhalb von 0,3 Ohm zeigt die LED rot. Gleichzeitig wird der gemessene Wert in einem Display (Schutzanspruch 2) angezeigt.The LED in the handheld device shows green if the measured value is within the permissible Range of 0.3 ohms. The LED shows red above 0.3 Ohm. At the same time, the measured value is shown on a display (protection claim 2) is displayed.

Nun werden die eingestöpselten Geräte nacheinander eingeschaltet.Now the plugged in Devices one after the other switched on.

Die Akustik (Schutzanspruch 1) meldet sich, sobald der gesamte Differenzstrom (in diesem Fall IPE) größer als 3,5 mA sein sollte.The acoustics (protection claim 1) report as soon as the total differential current (in this case I PE ) should be greater than 3.5 mA.

Der Anwender kontaktiert nun nacheinander die berührbaren metallenen Teile der Schutzklasse II-Geräte bei betätigtem S3-Taster (Schutzanspruch 2).The user now contacts the one after the other touchable metal parts of protection class II devices when the S3 button is pressed (protection claim 2).

Die Akustik (Schutzanspruch 1) in der BGVA2-Steckdosenleiste meldet sich, sollte der Differenzstrom (in diesem Fall IB) größer als 0,5 mA sein.The acoustics (protection claim 1) in the BGVA2 socket strip report if the differential current (in this case I B ) is greater than 0.5 mA.

Ein Ausführungsbeispiel der Erfindung wird anhand der Zeichnung 1 erläutert. Es zeigen:An embodiment of the invention is explained with reference to drawing 1. Show it:
